Title: Switching unit for high frequency signal
Inventor: OOHASHI MITSUO
IPC: H01P1/12
Filed: 1979-05-04
Abstract: PURPOSE:To make easy the discrimination of switching state, by performing mutual switching of input and output terminals through the U-link connecting cable and operating the display unit with the switch operated through this switching. CONSTITUTION:When the U-link connecting cables 6, 7 are connected as solid lines, the input terminal 1 and the output terminal 3, and the input terminal 2 and the output terminal 4 are mutually connected, and in case of connection as shown in chained lines, the input terminal 1 and output terminal 4, and the input terminal 2 and output terminal 3 are mutually connected. Further, since the protruding body 11 is attached near the end of the cable section 8 of the cable 6(7), this turns on or off the switch 10 such as a microswitch resulting in driving the display unit 12 such as a lamp. Thus, the switching state between a plurality of input and output terminals can easily be discriminated.

IPC: G02F1/136
Filed: 1980-04-28
Abstract: PURPOSE:To form a satisfatory light diffusing surface by using an alloy causing deposition by heat treatment as a material for an electrically conductive substance to be formed on a substrate as an electrode and applying the difference between the deposit and the other part in etching speed. CONSTITUTION:As said alloy an Al alloy contg. 2% Si is used. This Al-Si alloy deposits AlxSi1-x when heat treated. By dipping the alloy in an etching soln. after forming the deposit, etching is started from a part close to the deposit, and the surface of the alloy after dipping has the shape shown by the figure. Said surface is fit for light scattering, and a phenomenon that incident light is reflected from the surface >=2 times is hardly caused. The unevenness is controlled in size so that it can be flattened to a degree enough for the orientation of a liq. crystal by coating the surface with an insulating film and that it has a significant effect on light scattering.

Abstract: PURPOSE:To obtain a lightweight screw-shaped plastic molding anticorrosive, chemical resistant and electrically insulating with a high strength by crosslinking polyamide with a disintegrating polymer with the irradiation of radiation to lower hygroscopicity. CONSTITUTION:Polyamide (nylon or the like) and a disintegrating polymer (poly- 4-ethylene fluoride or the like) are mixed evenly in the form of a pellet or powder and for example, non-organic reinforcing fiber such as glass fiber and carbon fiber, a filling agent and various additives such as a treating agent for improving the adhesivity with fiber are added thereto as required. Such a plastic material undergoes an injection molding and extrusion molding in the shape of a bolt, for instance, and molded into a mere cylindrical material and rolled to mold a thread. When the threaded molding is irradiated with radiation, the main chain of the disintegrating polymer is cut off and the molding is crosslinked with an amide group to inhibit the water absorptibity of the molding resin.

IPC: F02D41/16
Filed: 1989-03-09
Abstract: PURPOSE:To make it possible to carry out an optimum idling rotation frequency control constantly by renewing the learning value responding to the difference between the first time from the shift change detecting time to the starting of a calculated control of the engine output and the second time from the above detecting time to the time when the load acts actually to the engine. CONSTITUTION:The idling rotation frequency is controlled to an object rotation frequency by controlling an ISC valve 45 in a bypass route 44 which detours a throttle valve 41, by a microcomputer 35 responding to the operating condition of an engine. In this case, when the shift change from one side to the other side of the driving range and the specific driving range of an automatic transmission is detected, a calculated control of the internal combustion engine output is carried out after the first time which consists by adding a learning value to a standard delaying time passes. And the second time from the shift change detecting time to the time when the idling rotation frequency is actually changed is detected, which is compared with the first time, and when the first time > the second time, the learning value is changed to the smaller value, and when the first time < the second time, the learning time is changed to the larger value.
